volume of a cylinder = V = πr²h, r = radius and h = height.
if r = 3 and h = 4, then V = π3²(4) => V = 36π => V ≈ 113.1.
Answer:
21.62% more
Step-by-step explanation:
20 mins * 3 = 60 mins (1 hour)
10 baskets * 3 = 30 baskets
3$ * 30 baskets = 90$
90$ - 74$ = 16$
74 / 100 - 0.74
90 / 0.74 = 121.62
So she makes 21.62% more with 3$ per basket.
25% of 42=25 divided by 100 x 42
25\100 x 42=10.5
Answer:
(a) 2% (b) 15
Step-by-step explanation:
(a):
80 - blue (32%)
60 - white (24%)
50 - red (20%)
45 - black (18%)
10 - silver (4%)
Total: 245
5 - other (2%)
(b):
60 - white
45 - black
Difference: 15
Here you have two terms connected by the "subtraction" symbol.
The two coefficients are 2 and 32, and one factor common to both of these is 2. Thus, <span>2x^2-32y^2 = 2(x^2-16y^2).
You could stop here. But it'd make more sense to continue, since x^2-16y^2 is easy to factor:
The three factors of </span><span>2x^2-32y^2 are 2, x-4 and x+4</span>
